Weegy: Y User: Mendel's principle of dominance suggests a_______gene will always be masked by the presence of a_______gene Weegy: recessive and dominant
User: Conducting a monohybrid cross of F1 generation plants, the recessive trait reappears in F2 plants in a ratio of _____.
Weegy: b.) 2:1 User: You can physically see the_______of a trait, but not the_______ User: You can physically see the_______of a trait, but not the_______
A. Genotype Weegy: You can physically see the phenotype, but not the genotype. User: A plant with the genotype TT is called _____.
User: A plant with the genotype TT is called _____.
A.homozygous
B.heterozygous
C.hybrid Weegy: The answer is A. User: You have a plant with yellow seeds, which express a dominant phenotype. How would you determine the plant's genotype?
Weegy: You should test cross with a purebread homozygous recessive plant.
Because your plant is Yy (heterozygous) or YY (homozygous dominant),
cross testing it with a yy will get you an answer. [ If you get all yellow phenotypes then the genotype for the plant in question will be homozygous dominant (YY) since crossing a YY with a yy will only lead you to Yy (Heterozygous) yellow plants. If you get any plants with the recessive trait then the plant in question MUST be Yy since only crossing a Yy with a yy will you get a plant that is homozygous recessive ] User: You have a plant with yellow seeds, which express a dominant phenotype. How would you determine the plant's genotype?
A.Conduct a Punnett square with a purebred recessive plant.
Weegy: You should test cross with a purebread homozygous recessive plant.
